Description

Liquid tank equipment for applying colored decors to the surface of objects

Field of technology

The invention relates to a liquid tank of a device for applying colored decors to the surface of objects by means of hydrostatic pressure of water in a liquid tank into which paint is poured on the liquid surface, or several paints which form a thin film of decor.

Prior art

For the application of colored decors on the surface of objects, a tank of solid shape or with solid inserted sides, filled with liquid, eg water, is used. On the liquid surface of the tank, a thin decorative film of one or more colors is formed between its side walls or firmly inserted sidewalls, which are poured by hand onto the liquid surface. Due to the surface tension of the liquid, resp. water, the colors spread very quickly on the water surface.

Before the formed decorative film of one or more colors dries, objects are inserted into the tank, the surface of which is decorated by adhering a color film to their surface.

The disadvantage of this manual method of creating a decorative film is the uncontrolled formation of a very thin - molecular layer of paint, or its components, which dries very quickly on the surface of the liquid. The dried paint does not allow further free spreading of the paint on the surface and must be removed mechanically by hand. This results in a relatively expensive decoration of objects due to the high consumption of paints for creating colored decors, or poor transfer of decor to the surface of the painted object. This process of spilling paint on the surface is almost impossible to reliably automate.

The object of the present invention is a device enabling the automation of the process of decorating objects, speeding up the process and reducing the consumption of paints for decoration.

The essence of the invention

The liquid tank of the device for applying colored decors to the surface of objects by hydrostatic pressure of water in a liquid tank consists in the fact that a level frame for pouring paint, or several paints, which form a thin film of decor, is arranged on the liquid tank surface. the side walls of the level frame is variable.

The side walls of the level frame are formed either by an elastic band enclosing the inner rollers, the relative position of which is variable, or by a rigid band enclosing the inner rollers, the relative position of which is variable, the rigid band passing between the outer rollers, or two crossbars whose relative position is variable.

Examples of embodiments of the invention

Figures 1a and 1b show a level frame inserted in a liquid tank 1 filled with a liquid, e.g. water. In Fig. 1a the area of the level frame for pouring decorative paint is at its minimum area, in Fig. 1b at its maximum area. The side walls of the level frame, which partially protrude beyond the liquid level in the liquid tank 1, are formed by an elastic band 7, e.g. a rubber band surrounding the inner rollers 5. By changing the position of the inner rollers 5 and thereby stretching the rubber band of the flexible border 7 frame from its minimum to maximum size. A decorative paint forming a thin film of the decorative layer 6 is poured into the surface frame. The decorative paint is first poured on the water surface to a minimum area in a thick layer. Subsequently, the decorative paint is spread over the surface by enlarging the area of the decorative paint and thus achieving the necessary reduction in the thickness of the decorative layer 6. The newly emerging decorative paint surface is then wetted with constantly fresh paint, which has minimal tendency to dry and adheres well to the elastic band. 7. This prevents the decorative paint from spreading spontaneously on the surface due to the surface tension of the liquid. After forming the decorative paint layer, colored objects are inserted into this decorative layer, which are surrounded by a decorative paint layer when they are immersed in a liquid tank.

Figures 2a and 2b show a level frame similar to the level frame according to Figures 1a and 1b, with the difference that its side walls are formed by a fixed belt 3, e.g. a rope or a belt, which surrounds the inner pulleys 5 and is guided between the outer pulleys. 4 arranged in front of the level frame. Here, too, by changing the position of the inner rollers 5 and thus increasing the length of the circumference of the fixed strip forming the frame, the area of the decorative frame changes from its minimum to maximum size and thus the decorative layer 6.

Figures 3a and 3b show a level frame which is formed by two longitudinal members 8 and two crosspieces 9, between which a surface is formed for pouring decorative paints and thus forming a decorative layer 6. Simultaneously changing the position of the longitudinal members 8 and cross members 9 decorative layer 6 from its minimum area in Fig. 3a to its maximum area in Fig. 3b.

Figures 4a and 4b show a level frame which, similarly to Figures 3a and 3b, is formed by two longitudinal members 8 and two crosspieces 9, between which a surface is formed for pouring decorative paints and thus forming a decorative layer 6. the size of the decorative layer 6 from its minimum area in Fig. 4a to the maximum area in Fig. 4b occurs simultaneously by changing the position of both crosspieces 9, or by changing the position of at least one of the crosspieces 9.

Fig. 5 shows an overall diagram of a device for transferring colored objects, where a level frame formed by longitudinal members 8 and crossbars 9 is arranged inside the frame 10 of the liquid tank 1. Facilitating the process of applying colored decors to the surface of objects allows transferring colored objects 12 to the surface frame by arm. robot 11.

Liquid tank equipment for applying colored decors to the surface of objects with surface

- 2 CZ 308736 B6 frame according to the invention has many advantages over existing devices, which make it possible to fundamentally influence the quality of the paint layer on the surface and thus the decor on the surface of the object.

The process of spilling decorative paints on the surface in a liquid tank can be controlled and thus enable the whole process, including dipping of decorated objects, eg by automation with the help of a robot. Another advantage is the ability to control the thickness of the decorative paint and the size of the area of the decorative paint. It is thus possible to achieve higher stability of the decorative paint, thanks to the fact that some components are not prematurely excreted. Furthermore, it is possible to repair the defects of the decorative paint layer by reducing the area of the decorative frame again.

Other advantages are the possibility to change the shape of the surface according to the shape of the painted object - square, rectangle, trapezoid, the possibility of reducing the color area during the immersion process and thus dosing a more uniform thickness and moving the frame with colored decor across the surface.
